Yes, I'm okay with that.  The current behavior is definitely wrong
from an authoring perspective, so I want to at least put in the effort
to get it right, even if practicality means that we end up having to
go with current behavior.

Just to demonstrate the current behavior, I've created an example page
 (Only FF and IE can even render these correctly, though - both Chrome
and Opera screw up on the pre cases.  Chrome doesn't group the two
rows together into a single table, and Opera wraps every run of
whitespace in an anonymous table-cell.)

In an ideal world, the abspos "bar" cell would *not* create a
table-cell in the table it comes from, so that, for example, in the
top-left case the second row would have "baz" below "bar" (rather than
an "empty" space below bar, where an anonymous empty table-cell sits).
